Nitrogen & Oxygen Generators

Membrane nitrogen generators for easy, cost-efficient gas generation Atlas Copco’s membrane nitrogen generator (the NGM) is, thanks to its high efficiency and reliability, ideal for applications such as fire prevention, tire inflation, tank and pipeline cleaning, and many other oil and gas, mining and marine applications. The NGM uses membrane air separation to produce nitrogen. A bundle of polymer fiber acts as a membrane that allows nitrogen to pass and other gases (like oxygen, water vapor and carbon dioxide) to permeate. Compressed air goes in at the inlet and enriched nitrogen comes out at the other end of your nitrogen generator. Membrane technology generates nitrogen with an adjustable purity and flows up to 500 m³/h.

PSA nitrogen generators for the highest purity For those applications that demand high purities of nitrogen (up to 99,999%), the Nitrogen Generator (NGP) with PSA technology is the recommended solution. Based on the Pressure Swing Adsorption (PSA) technology, carbon molecular sieves adsorb oxygen molecules from compressed air. The Nitrogen Generator has two connected towers that work together to produce an almost continuous flow of nitrogen gas. The result: nitrogen purity levels up to 99,999% for flows up to 1100 Nm³/h. Typical applications of the NGP are packaging, plastic molding, metallurgy, purging analyzers, electronics, fruit storage and food and beverage.

PSA oxygen generators for reliable, on-site oxygen Oxygen is vital to processes in the medical world, in waste water treatment, fish farming and ozone production. The OGP oxygen generator also makes use of PSA technology, with zeolite pellets that act as adsorbent. The output is oxygen with an adjustable purity between 90% and 95%, at flows up to 200 Nm³/h.

On-site nitrogen and oxygen as part of a total solution Atlas Copco now offers on-site gas generators which can be directly combined with an existing compressed air installation. With an independent supply of nitrogen and oxygen, companies can start saving on the operational and administrative costs of bulk and cylinder gas delivery. These 3 ranges of nitrogen and oxygen generators offer exactly the flows and purities that different industrial applications need. This way, Atlas Copco becomes a one-stop-shop for compressed air, gas and service.
